Default Sporadic heat issue help!!

2007 Lexus RX350
I've been trying to figure out why my car's heater isn't operating normally,, I have ruled out everything, it's not the HVAC controls
The Thermostat was Faulty(Zero Heat), Replaced it,
Now I get Heat but it takes twice the normal time to get Heat from the vents,if I hold my foot on the accelerator it gets very Hot, but at idle it's barely Warm, I should add No coolant leaks
I'm 99% sure that I need a New Water Pump (Aisen OEM)
Should I replace the drive belt idler pulley and tensioner pulley while I'm in there?Do they need to be Aisen brand also? Having trouble locating the idler and tensioner pulley part numbers,any info appreciated!
